JOHN N. PARKER AND IRVIN MAYIBERRY, 0F DUQU'OIN, KANSAS.

FEEDER FOR THRESI-IINGr-MACHINES.

Application filed May 13, 1915.

To all whom it may concern:

Be it known that we, JOHN N. PARKER and IRVIN MAYBERRY, citizens of the United States, residing at Duquoin, in the county of Harper and State of Kansas, have invented certain new and useful Improvements in Feeders for Threshing-Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the ticularly to means for feeding the un-- threshed grain into the same. Heretofore it has been necessary to perform this feeding operation, or at least a part thereof, by the use of hand forks, this being aneXtremely slow and tedious process.

It is the object of the invention, therefore, to improve upon the construction of feeders to such an extent as to totally obviate the 7 use of hand forks for feeding the unthreshed grain into the threshing machine. In accomplishing this end, we provide certain novel features of construction and combination hereinafter described and particularly pointed out in the appended claims.

In describing the invention we shall refer to the accompanying drawings wherein like reference characters designate corresponding parts throughout the several views, and wherein Figure 1 is a side elevation of a machine constructed in accordance with our invention, the two side conveyers thereof being disposed to horizontal position; Fig. 2 is a top plan view with the parts positioned as shown in Fig. 1; Fig. 3 is a front end view showing the side conveyors swung upwardly to a greater extent than that shown in the preceding figures; Fig. l is a rear end view with the conveyers disposed as shown in Fig. 3; Fig. 5 is a central vertical longitudinal section; Fig. 6 is a vertical transverse section as seen along the plane indicated by the line 66 of Fig. 1; with the vertically oscillatory rakes disposed to their uppermost positions; Fig. 7 is a detail vertical transverse section showing one of the rakes swung downwardly; Fig. 8 is an end view of the machine with the several parts thereof disposed for transportation.

In these drawings, constituting a part of the application, 1 designates a truck upon Specification of Letters Patent.

which is supported a horizontal elongated conveyer trough or frame 2 having at its front end a transverse shaft 3, and at its rear end a similar shaft 4 having means, such for instance as the pulley 5, whereby it may be rotated. Both of the shafts 3 and 4; are provided with sprocket wheels 6 disposed at the ends of the trough 2, said wheels being provided for the guiding and driving of .an endless conveyer 7 shown in the present application as comprising longitudinally disposed chains passing over the sprocket wheels 6, and transverse slats secured at their ends to said chains. It will thus be evident that as the shaft 4 is rotated in the proper direction, the upper stretch of the conveyer 7 will be moved rearwardly, thus shifting the unthreshed grain deposited thereon by means to be described, to the rear of the trough, at which point the bands on the numerous bundles of grain are cut by any preferred type of driven band cutter 8.

Spaced outwardly from the sprockets 6 the drive shaft 4 is provided with bevel gears 9,

which intermesh with similar gears 10 secured to one end of a pair of longitudinal shafts 11 which are spaced outwardly from the sides of the trough 2 and rotatably mounted in bearings 12 carried thereby, at the opposite end thereof. The opposite or front ends of the shafts 11 are provided with spur gears 13 which intermesh with additional spur gears 14: secured to the front ends of upper longitudinally disposed conveyer shafts 15 which are spaced above and lie parallel to the shafts 11 as shown.

Pivoted at their inner ends to extensions 12 of the bearings 12 is a pair of side conveyer frames 16, such frames being thus mounted to swing vertically to the several positions shown in the drawings, and to ad ditional altitudes. Each frame 16 is formed of an inner section 17 and outer section 18 hinged thereto at 19, the two sections being normally retained in alinement by bolts or the like 29 passed through appropriate keepers at the ends of said sections.

The outer sections 18 are provided with hearings in which longitudinal conveyer shafts 21 are rotatably mounted, such shafts being disposed parallel to the shafts 15 and-the two shafts being provided with guide sprockets 22 around which the endless chains of the side conveyers 23 are passed, such conveyers thereby passing around the inner and outer frame sections 17 and 18 and beingdriven while the pins 29 in. such a manner as to cause their upper stretches to move inwardly toward the conveyer 7 while the lower stretches move outwardly to shift any grain upon which the frames 16 rest, outwardly and toward the ends of said frames, at which points the grain is gathered by means yet to be described.

The aforesaid gathering means is in the form of a pair of rakes 24 disposed parallel to the outer ends of the side frames 16, such rakes being mounted to shift inwardly and outwardly toward the outer ends of said frames and to oscillate vertically in respect thereto. In the present embodiment of the invention, the curved teeth of the rakes 24 are shown as projecting outwardly from rock shafts 25 whose ends are mounted in elongated guide yokes 26 disposed longitudinally of the frames 16 and located at the lower corners thereof. By elongating the yokes 26 in the manner shown and described, .and by forming the ends of the rock shafts 25 of the proper proportions, such shafts mayv not only rock within said yokes but may shift inwardly and outwardly therein, thus 'shiftingthe teeth of the rakes inwardly and outwardly in respect to the outer portions of the conveyers 23. For the purpose of i1nparting this movement to the rock shafts 25 and therefore to the rake teeth carried thereby, the opposite ends of said shafts are provided with cranks 27 disposed in planes below the rock shaft and connected by removable pitman rods 28 to crank pins 29 and 29*, the pins 29 being carried by the gears 14, are mounted eccentrically upon disks 14* secured to the ends of the shafts 15'remote from the aforesaid gears 14.

When the shafts 15 are rotated to drive the conveyers 23, the eccentric crank pins 29 and 29 thereon will reciprocate the pitmen 28,

thereby shifting the rock shafts 25 outwardly within the guides 26 and simultaneously rocking themito raise the rake teeth, and'then shifting said rock shafts again inwardly, thus rocking them in the opposite direction to move the rake teeth downwardly, thereby'drawing a quantity of the grain inwardly to be conveyed to the trough 2,,by the conveyer 23.

In applying the invention to use, the entire machine is disposed between two stacks S of unthreshed bundles of grain, and one of the side conveyer frames 16 is raised and disposed upon each stack. The thresher is then properly positioned to allow the conveyer 7 to deliver into the same, and both machines are set in operation. The result is that the upwardly moving lower stretches of the conveyers 23 gather the bundles of grain on which they are resting and move the same outwardly to the rakes 24, the latter bemgnow reciprocated inwardly and outwardly in the manner previously set forth and drawing additional bundles inwardly, all of these bundles being then carried to the conveyer 7 by the inwardly moving upper stretches of the aforesaid conveyers 23. The conveyer 7 now carries the bundles to the band cutter 8, beneath which they are passed and finally fed into the thresher. Needless to say, should it be found desirable, only one of the side conveyers 16 need be used.

When transporting the machine from place to place, the bolts 20 are withdrawn, the pitman. rods 28 are removed, the outer sections 18 of the frames 16 are folded inwardly upon the inner sections 17 thereof, the latter are swung downwardly, and the sections 17 and 18 are retained in folded position by hooks or the like 20 (see .Fig. 8).

From the foregoing description, taken in connection with the accompanying drawings, it will be evident that although a comparatively simple machine has been provided for carrying out the object of the invention, the same will be very efficient in operation and will possess a number of highly advantageous features. Particular emphasis is laid upon the mounting and manner of operation of the gathering rakes and the actuating means therefor, since this isone of the most salient features of the invention.

In the drawings, we have shown certain specific details of construction for accomplishing probably the best results, and in the foregoing have described such details, but it will be evident that we need not be limited thereto otherwise than to the extent to which the appended claims limit us.

We claim 1. A machine of the class described comprising a conveyer frame, an endless c011- veyer passing around the same, an inwardly and outwardly shiftable rock shaft disposed at one end of the frame and lying parallel thereto, a rigid crank carried by said rock shaft, reciprocatory means connected to said crank, whereby to simultaneously shift inwardly and outwardly and oscillate the same and rake teeth ro'ectin from said shaft and spaced outwardly from the aforesaid end of the frame.

2. A machine of the class described comprising a conveyer frame, an endless conveyer passing around the same, a pair of elongated guide yokes disposed at one end of the frame, an inwardly and outwardly shiftable rock shaft likewise disposed at said end of the frame and lying parallel thereto, the ends of the shaft being mounted for lateral shifting and oscillation in the aforesaid yokes, a rigid crank on said shaft, reciprocatory means connected to said crank, whereby to simultaneously shift the shaft inwardly and outwardly and oscillate the same, and rake teeth carried by said shaft and projecting outwardly from the aforesaid end of the conveyer frame.

3. A machine of the class described com prising a vertically swinging conveyor frame, a transverse driven shaft at the pivoted end thereof, cranks on the opposite ends of said shaft, sprocket Wheels on the intermediate portion thereof, additional sprocket Wheels at the free end of the frame, an endless belt conveyer trained around the first and last named sprocket Wheels, a pair of elongated guides carried by said free end of the frame and positioned in transverse alinement, a transverse rock shaft mounted for oscillation and lateral shifting in said guides, cranks on the opposite ends of said rock shaft, pitman rods connecting the first and last named cranks, and rake teeth projecting laterally from the rock shaft and having downturned ends spaced outwardly from the free end of the conveyer frame.
